Editing Groups and Components - Square One

hey guys i'm aaron and this is sketchup square one where we take a look at the basics of using sketchup today i wanted to kind of combine some of the information we've covered already so i'm going to look at using the scale tool and groups and components so there's something specific about the way edits to containers work as it relates to groups and components so this is important enough that i felt like it deserved its own video so let's go ahead and hop in and talk about editing groups and components all right so i created some geometry here uh i just wanted something that wasn't uniform and gonna look the same once you know you spin a cylinder turn it something like that it looks the same you scale a box it looks the same so i wanted some some non-symmetrical geometry so i created this little cylinder with a house shape butting into it so this is my original this is my control i just created this this is just raw geometry sitting here um i wanted to reference back to this potentially as we move through here over here i have a group marked with the g and a component marked with a c so of course just because it's how they work i'm going to go ahead and use the move command i'm going to hit my modifier key to make a copy and i'm just going to make a second copy because this is how components work right is they're linked together so this these are two copies of the same instance so a change to one will affect the other all right let's hop in here and start talking about this so when i modify when i talk about modifying a group or component i'm talking about the actual container not the geometry inside the geometry inside is just geometry just like what we have over here so if i just double click to open this group now if i came in and moved this there's really nothing special about this i could move this geometry however i want i can you know make whatever changes i need to to this geometry and because i'm editing geometry inside of a group it doesn't really there's nothing special that happens i change that geometry and then when i leave the group it's changed but there are some things that when i make changes to them they have other impacts let me explain what i'm talking about i'm trying to explain something rather than just showing just showing will probably be easier all right when i enter this group i have my geometry and look at my axis so my axis my axes right here the red blue green axes is going the same direction as if i click out of here right green's going this way red's going this way blue's going this way same thing it slides over so it's in the container but you can see it goes the same direction so if i take this group from the outside so not not double clicking to enter but right here from the outside i grab my rotate command and i rotate it this amount 37 degrees approximately no any any angle you rotate it to watch it happens if i double click and come in here look at that my axes rotated along with the component the i'm sorry the group so this is important because when i come in here if i want to say i want to uh let's say i'm going to grab this g and i want to move it i can move along the red or green axis the same way i did before because that red and green axis stayed aligned to the geometry inside the group right if i take this geometry right here triple click and i rotate this guess what this line is no longer parallel to the red axis it is now parallel to whatever i just rotated it to so that is a very important piece to note about working with components or groups is if you make those kinds of changes you're only changing what's on the outside now with groups that has limited impact right the impact there is if i come in here to modify this geometry it's easy because all my geometry still aligns to my axes with components there's something that's a little bit different right so here let me let me show you this so if i grab this one and do the same thing i'm just going to rotate this component that's what happens right so if i was to come in here and do the same thing grab this grab the c now if i go to move it i can move it along those axes but look at look at this one over here see this guy because they're components and they're linked they're going to move together but this c is not going to move off at some weird angle it's moving parallel to the axis inside of the component so it makes a big bigger difference with these kind of pieces with components but here i'm going to go ahead and undo a couple times here is a much bigger impact and this is this was the reason that i decided to make this video if i select this component and i come hit scale and i scale it up like this when i release look they didn't change because what i just scaled right here was the container i scaled the outside of this piece not the geometry on the inside i'm going to undo and show you the difference if i double click here and now i grab all this geometry and then i hit scale now i'm scaling the geometry inside the instance so every copy of this is going to get scaled the same if i come back outside and i hit scale and let's say do something weird like just grab one axis and squish it like this that geometry stays exactly the same and here's the weird part okay so let's let's take this one right here uh deselect that grab this guy rotate him right so i have these two very different looking components but watch this if i come in here and i do the same thing i did before i grab that c and i go to start moving it around look what's happening on my my squished version i'm getting the squished equivalent of this move along its face so that deformation to the container is kind of a after-market change so what's happening is the geometry inside there is still linked but this version of it is being distorted after it's drawn so very important to understand how that works we have people ask these questions all the time well i went and i changed but this change didn't affect other components or why did this change that component when this one was a different size that sort of thing this is why changes to the container will not affect other copies of the components any change to geometry inside will so hopefully that made sense like i said there's there's some confusion some people get kind of hung up on on inside and outside of containers and groups versus components hopefully it's another step towards that making more sense they're incredibly useful tools you can do some really cool stuff once you grasp exactly how to use groups and containers along with the modification tools inside sketchup hopefully like that video if so go ahead and click like down below and if you haven't already please subscribe we create several videos each and every week and you'll be notified of them all if you subscribe most importantly they'll leave us a comment down below do you like these videos is there something else we should have shown do you have a request for what you'd like to see on one of these we like making these videos a lot we'd like them even more when they're showing something you want to see thank you you
